Oil Surge Relay for Transformer | OSR Relay

Oil Surge Relay for Transformer – High Performance Transformer Protection Device

Overview

The Oil Surge Relay for Transformer is a critical transformer protection device designed to detect sudden internal faults in oil-filled transformers. This advanced Oil Surge Relay (OSR Relay) is widely used in power and distribution transformers to ensure safety, reliability, and uninterrupted performance. As a leading Oil Surge Relay manufacturer and supplier in India, we provide high-quality OSR Relay solutions suitable for various industrial and utility applications.

Installed between the conservator and transformer tank, the Oil Surge Relay for transformer continuously monitors oil flow conditions. In case of abnormal oil movement caused by internal faults, the oil surge relay immediately activates the trip mechanism, making it an essential transformer safety device.

 

What is an Oil Surge Relay?

An Oil Surge Relay is a specialized transformer protection relay that detects sudden oil flow inside the pipeline. During internal transformer faults such as winding failure, insulation breakdown, or short circuit, the oil moves rapidly. The Oil Surge Relay for transformer senses this surge and sends a trip signal to isolate the transformer.

This oil flow relay for transformer plays a vital role in preventing major damage and improving system reliability, making it a preferred choice for transformer manufacturers and electrical industries.

 

Key Features of Oil Surge Relay

  • High sensitivity Oil Surge Relay for Transformer
  • Instant fault detection with OSR Relay mechanism
  • Durable and corrosion-resistant construction
  • Reliable transformer protection relay performance
  • Leak-proof and weather-resistant design
  • Suitable for power and distribution transformers
  • Low maintenance transformer safety device

 

Working Principle of Oil Surge Relay

The Oil Surge Relay for transformer operates based on oil flow velocity. Under normal conditions, oil circulates smoothly. However, during faults, a sudden surge of oil occurs.

This oil surge relay uses an internal flap mechanism that reacts to oil pressure. When triggered, the OSR relay activates electrical contacts, sending a trip signal to disconnect the transformer. This fast action makes it a highly efficient transformer protection device.

 

Applications of Oil Surge Relay

  • Power transformer protection systems
  • Distribution transformer safety
  • Electrical substations and power plants
  • Industrial electrical networks
  • Transformer accessory installations

The Oil Surge Relay for transformer is widely used across industries requiring reliable transformer protection relay systems.
